How it's made
- Source
- rock slab splitting under pressure. A low rumble (brown noise, 40–180 Hz, plus a 38→55 Hz sub swell) builds for ~0.3 s while the ground heaves; each spike is a short noise burst of fracturing grains.
- Body
- grinding crack = band-passed noise (500–3500 Hz) chopped by a random stick-slip gate, its centre rising as the fracture opens; every spike excites a dense, short-ringing stone mode bank (size sets pitch) plus a 130→50 Hz thump from the displaced mass.
- Envelope
- rumble swells 0.3 s, spikes erupt 0.22–0.75 s in a rapid staggered burst, then everything is cut in a few tens of ms when the spikes lock in place (the "sharp stop").
- Variation
- `rng` jitters spike timing, strength, mode tuning and the grain gate; presets change spike count, rock size, grind and rumble weight.
